NAILING-STRII.

Application filed April 15, 1919. Serial No. 290,166.

To all whom it may concern:

Be it known that I, HIRAM E. BARBER, a citizen of the United States, residin at Sheridan, in the county of Sheridan, tate of W oming, have invented a new and useful ailing-Strip; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a nailing strip, and has for its object to provide a device of this character which embodies novel features of construction whereby it can be stamped from a sheet metal blank without waste and will provide an effective means for securing roofing sheets or the like in position.

Further objects of the invention are to provide a nailing strip which can be read ily driven in position and will become securely anchored upon the wood or other material so that there is no danger of the strip being accidentally pulled from position, and which will extend over the edges of the roofing material or the like so that itwill be held down and prevented from being blown up and torn by the wind.

With these and other objects in View, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawin s, in which igure 1 is a top plan view of a portion of a nailing strip which is constructed in accordance with the invention, a second nailing strip being indicated by dotted lines andarranged to show the manner in which successive nailing strips can be cut from a blank of sheet material without waste.

strip will fit in the restricted Patented Nov.

I Fig. 4 is a plan view of 'a slightly modified form of nailing strip.

Fig. 5 1s a transverse sectional view on the line 55 of Fig. 4.

The nailing strip which is designated by the reference character A is formed from sheet metal and is shaped with alternately arranged restricted neck portions 1 and wide portions 2, said neck portions and wide portions being equi-distantly spaced and avmg a corresponding and symmetrical formation so that the wide portion of one ortion of another strip at one side thereo In Fig. 1 a second strip is indicated by dottedlines and this figure shows the manner in which the large portions of one strip fit against the-restricted neck portions of another strip, thereby enabling these nailing strips to be stamped or cut from a sheet metal blank without any waste. This enables the nailing strips to be economically manufactured and handled without loss. A driving point 01' prong 4 is stamped from each wide portion of the strip and deflected downwardly, and these driving. points are crimped or bent longitudinally in such a manner as to straighten and reinforce the same so that they can be readily driven into a wooden roof or floor without danger of buckling or collapsin during the dIlVll'l operation. As indicate most clearly by ig. 6, these prongs 4 may be transversely bent so as to ave an angle iron or V-shaped cross-section, thereby stiflening them so that they can be readlly driven mto position. Alternate prongs 4 have the pointed ends thereof beveled in opposite directions, as indicated at 5. This will cause alternate pron s or driving points to be deflected lateral y in opposite directions as they are driven into the wood, as indicated by 'Fig. 3, with the result that the driving points will securely anchor the strip to the roof or floor so that there will be no danger of the strip being v accidentally pulled or removed from position.

A sli ht modification is shown by Fig. 4, in whic portions of the strip between the prongs or driving points 4 are bent or arched transversely, as indicated at 6. T h1s is indicated more clearly by Fig. 5 which is a sectional view. This stifi'ens and reinforces the portions of the nailing strip between the prongs so that these intermedlate portions of the strip will hold the roofing sheet or the like firmly in position and w ll not bend or bulge upwardly. The strip can, however, be readily bent or flexed at the flat portions thereof between the arched portions 6, thereby enabling the strip to be handled and applied to a roof, floor or'the like without difiiculty.

A further modification is illustrated by Fig. 7, in which the prong or driving point 4 is shown as having opposite longitudinal edges thereof returned at 7 to stiffen and reinforce the same.

In order to accomplish this result, the upper ends of the folded longitudinal edges 7 of the driving points are severed or cut away from the body of the strip as indicated at 7. It will be obvious that there are many different manners in which the sheet metal prongs can be longitudinally bent or crimped to stiffen and reinforce the same,

and when the driving points are thus reinforced it may be possible to use a lighter weight sheet metal stock in manufacturing the nailing strips. This may result in a ver appreciable economy. It will also be un erstood that there are many other variations and modifications of the invention which are within the scope of the claims, and that the invention is not in any manner Lasaoae downwardly, alternate driving points having the pointed ends thereof beveled in opposite directions so that they will be deflected laterally in opposite directions as they are driven in positlon,

2. A nailin strip formed of a continuous narrow length of sheet metal which has a series of driving points stamped therefrom at intervals and bent downwardly, said driving points each having a longitudinally extending stiffening and reinforcing bend therein.

3. A nailing strip formed of a continuous narrow lengt of sheet metal and having alternately restricted neck portions and wide portions, the wide portions of the strip havin driving points struck therefrom and bent ownwardly and the portions of the strip between the drivin points being transversely arched to rein orce and stiffen the same, said driving points being each formed with a longitudinally extending stiffening and reinforcing fold.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
